CENTRIFUZGAYL OILER.

SPECIFICATION forming part of LettersPatent No. 447,282, dated February 24, 1891.

Application filed April 2, 1890. Serial No. 346,263. (No model.)

T0 at whom it may concern.-

Be it known that 1, CHARLES O. HEGGEM, a citizen of the United States, and a resident of Massillon, county of Stark, State of Ohio, have invented a new and useful Improvement in Centrifugal Oilers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to improvements in centrifugal oilers for traction and portable engines; and it consists in certain features of construction and combination of parts, as will be hereinafter described, and pointed out in the claims.

Figure 1 of the accompanying drawings is a side elevation, partly sectional; Fig. 2, an end elevation, and Fig. 3 a view of detail hereinafter explained.

Similar letters of reference indicate corresponding parts in all of the figures of the drawings.

As my invention is applicable to many of the traction and portable engines now in use, I will proceed with a description thereof, referring to the engine parts only as conjunctional thereto.

A represents a portion of a traction-engine boiler; B, a pedestal-support for a journalbox, in which the engine-shaft O is supported and rotated D, the crank-plate, E, the wristpin, and F the connecting-rod.

The object sought by this invention is to provide means for oiling the wrist-pin during long runs on the highway, as Well as during the long periods of use when driving thrashing-machines or other machinery, when to stop for such purpose would result in great inconvenience as well as loss of time; and to this end I have provided an arm-support, as G, secured to the side of the boiler Aand extended outwardly to a point outside of the crank-pin E, then upwardly to a point on line with the top portion of the shaft 0, or there about, and for the purpose of this case and to avoid expensive repairs in case of accident I have made this aim in two parts-an arm part Gr and a shoulder part H. The shoulder or body portion H is secured to the boiler A, as shown in Fig. 1, and has in its outer face portion a groove a, the sides b of which are undercut or dovetailed and slightly converged at the bottom to form a groove tapering sidewise from the'top to the bottom.

At the lower end portion of the arm G is provided a dovetailed wedge-shaped portion d, adapted to pass into the groove a and en gage the sides I), and is secured therein by the set-screw h, as shown in Figs. 2 and 3. The top portion of the arm G is provided with a vertical passage and a communicating horizontal aperture m. In the former is placed an oil-cup n and in the latter a tube 0, hereinafter explained. In the end of the wrist-pin E is provided a central passage 19, having an annular screw-thread, as shown, said aperture extending longitudinally with said pin to a point about central to the journal portion thereof, at which point it is intersected by passages g, transverse to said pin and leading from the aperture 19 to the outside of the pin E, as shown in Fig. 1.

The cap K is provided with a socket or cup portion 0' to receive and embrace the end portion of the wrist-pin and an arm portion 8, apertured as shown in Fig. 1. Said cap is secured to the wrist-pin by a screw-bolt t, turned into the threaded aperture 19, said bolt having a central longitudinal aperture to and perforations to correspond with the aperture 0 in the arm 8. The arm .9 is placed parallel with the plate D, the perforation to central to the shaft, and the tube 0 in said perforation.

By providing an adjustable supporting-arm I am enabled to geta true adjustment of the tube 0 with respectto the arm 8, in order that the outlet of said tube may be in a direct line with the bore or channel of said arm. This I find to be an important feature, for as the parts connected to the wrist-pin wear I can compensate for such wear by adjusting the bracket-arm G.

In operation oil is placed in the cup or, from which it is fed in the usual way and passes through the tube 0 into the arm and is driven by the centrifugal force through the apertures 12, u, and g to the periphery or journal portion of the pin, at which point the oil is utilized to lubricate the wrist-pin and its box.

Having thus fully described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is-

arm communicating with said wrist-pin, an adjustable arm having a vertical and transverse passage, an oil-cup arranged in the vertical passage, and a tube for conducting the oil from the transverse passage to the hollow arm, substantially as set forth.

In testimony whereof I have hereunto set my hand this 31st day of March, A. D. 1890.

CHARLES O. HEGGEM.
